Best bang for buck tune on an HW85/95...

[silva]

Just short stroked the 85


Fitted one of Tinner's delrin short stroke noses to my 85, along with a Wonky Donky spring (hope I'm not breaking any advertising rules by mentioning these two chaps, but I'm really just reviewing a nose extension and a spring)...

I went for the 12mm as mines a .22, and that takes the stroke from 86mm to 74mm. For camparison a 99 is 71mm (both are 26mm bore).

Wow Loverly to fire, soft and quick at the same time, easy to cock and blistering accurate with superdomes.

For the tiny outlay of a spring and a nose ext, this will literally transform the flippy, hold sensitive 85/95 into a tack driver.

With hindsight I think going for the 10mm might have been a smarter idea, as the piston is a little heavy, and the extra 2mm of stroke would help to soften it a bit more. Also, you just notice the "slack" movement when cocking at the begining of the stroke - but only just. With a 2mm shorter nose (i.e. 10mm instead), I reckon you wouldn't feel it at all. I'd defo go for the 10mm in .177 regardless.

So there you go; about the best bang for buck I've ever seen in the field of spring gun tuning.

Hi Sorry to resurrect an old thread. I'm up for a similar tune - Is the Wonky Donkey spring the one to go for ? - Cheers

they are good springs, but personally I like to change one thing, see how it shoots, then use that information to inform the next change. Start with the short stroke.. you may find you are very happy with the firing cycle, and all it needs is (for example) is a twang reduction courtesy of a better fitting rear guide. Or you may find it too harsh, and a softer spring is the way to go. Lots of variables, not least calibre, barrel length, and personal preference...
